Anyone knows how to do it? It doesn't inherits openbox's settings so i tried advices, related to other unity/gnome (maybe chrom* inherits it):
$ gconftool-2 --get /apps/metacity/general/button_layout
close,minimize,maximize:
$ gsettings get org.gnome.desktop.wm.preferences button-layout
'close,minimize,maximize:'
$ gsettings get org.gnome.shell.overrides button-layout
No such schema 'org.gnome.shell.overrides'
But buttons still on the right side. And I still don't want additional useless native decorator.
